Item 4.01.         Changes in Registrant’s Certifying Accountant

On August 14, 2012, the Audit Committee of the Board of Directors of Quicksilver Resources Inc. determined not to reappoint Deloitte & Touche LLP as Quicksilver’s independent registered public accounting firm.

Deloitte’s reports on Quicksilver’s financial statements for the fiscal years ended December 31, 2011 and 2010 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

During the fiscal years ended December 31, 2011 and 2010 and through August 14, 2012, there were no disagreements, within the meaning of Item 304(a)(1)(iv) of Regulation S-K, with Deloitte on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, that, if not resolved to Deloitte’s satisfaction, would have caused Deloitte to make reference to the subject matter thereof in connection with its reports on Quicksilver’s financial statements for such years.

During the fiscal years ended December 31, 2011 and 2010 and through August 14, 2012, there were no reportable events as described in Item 304(a)(1)(v) of Regulation S-K, except for material weaknesses described in Item 9A of Quicksilver’s Form 10-K for the year ended December 31, 2011 and Item 4 of Part I of Quicksilver’s Form 10-Q’s for the quarters ended March 31, 2012 and June 30, 2012.  The Audit Committee discussed these material weaknesses with Deloitte and authorized Deloitte to respond fully to any related inquiries by Ernst & Young LLP, Quicksilver’s new independent registered public accounting firm.

Quicksilver provided Deloitte with a copy of this Form 8-K and requested that Deloitte provide Quicksilver with a letter addressed to the Securities and Exchange Commission stating whether Deloitte agrees with the above disclosures.  A copy of Deloitte’s letter is attached as Exhibit 16.1 to this Form 8-K.

On August 16, 2012, Quicksilver engaged Ernst & Young LLP as its independent registered public accounting firm for the fiscal year ended December 31, 2012.  During the fiscal years ended December 31, 2011 and 2010 and through August 16, 2012, neither Quicksilver nor anyone acting on its behalf consulted with Ernst & Young regarding any of the matters described in Item 304(a)(2)(i) and (ii) of Regulation S-K.
